According to MD club is also in negotiations with Vicky Lopez. Her contract is expiring next year and is surely amongst priorities alongside Ingrid Engen and Irene Paredes.
Other players on expiring contracts are Keira Walsh, Marta Torrejón, Gemma Font, Jana Fernández and Martina Fernández,
Walsh will almost certainly return home for familiar reasons but hopefully club can convince her to stay. Don't think there should be problems to renew Marta if the club will want to keep her but they'll probably wait until later in the season to also know what her intentions are. At her age it's possible she'll want a new challenge or go somewhere to play more.
Gemma will be a 3rd GK when Roebuck is ready to play and at almost 25 is possible she'll look for a new club. Martina quite established herself last season while Jana again struggled with injuries. We'll see how this season will go but think club would like to keep them both and then maybe loan one of them to get more playing time. Probably won't get much minutes here behind Mapi, Irene and Ingrid.
